Title: Improvements in and relating to tobacco leaf forwarding and controlling mechanism, for tobacco leaf stemming machines
IPC: A24B5/12
Filed: 1936-04-06
Abstract: 464,718. Tobacco-stemming machines. INTERNATIONAL CIGAR MACHINERY CO. April 6, 1936, No. 10077. Convention date, Jan. 25. [Class 130] [Also in Group XXX] A device which coacts directly with tobacco leaves which advance in succession controls mechanism by which the unstemmed or insufficiently stemmed leaves are removed from the path of the properly stemmed leaves. Tobacco leaves L emerging from a stemming machine, such as that described in Specification 380,496 in which the thin tip portions of the stem are left in the leaves, are fed by a belt 5 beneath a detector roller 6. The stems in the leaves are crushed while passing between a fixed roller 16 and a roller 18 carried by a cam-actuated arm 20 and the surfaces of the rollers 16, 18 are cleaned by felt pads 24 moistened with water from a reservoir 25 and by scrapers 23. The leaves are delivered to a pair of transfer belts 27 between which is an anvil disc 34 on which the crushed stem tips are held by belts 40 and split by a cutter 35 carried by a cam-actuated arm 37. To enable the belts 27 to deliver the properly stemmed half leaves on to belts 53 and the unstemmed or insufficiently stemmed half leaves on to belts 55 from which they fall into a trough 59, the rollers 54 supporting the belts 55 at the end adjacent the belts 27, are carried by pivoted arms 60 and are moved out of alignment with the belts 27 as each properly stemmed leaf is fed. An unstemmed or insufficiently stemmed leaf lifts the roller 6 to close contacts 14, 14a which, through mechanism similar to that described in Specification 441,588, closes the circuit of a solenoid and prevents a spring 69 operating a lever 65 to raise the belts 55. The stemmed leaves on the belts 53 are compressed and flattened by belts 95 as they are guided over the upper wall of a suction chamber 92 and around a drum 93 and are held against the belts 53 by suction while travelling beneath the suction chamber. When the suction in the chamber 92 is cut off by a valve 112 the half leaves are deposited, preferably in overlapping relation, upon travelling screens 106 or a conveyer belt by a plate 122 which is lowered in the chamber 92 by a cam 117. As the plate descends, bars 124 move between the belts 53 and engage the half leaves and force air through the perforations in the belts. Specification 465,577 is referred to.

IPC: H03B11/06
Filed: 1917-07-12
Abstract: 117,480. Hecht, N. F. S., and Creed & Co. July 12, 1917. Transformers.-High-voltage discharges are obtained by connecting a condenser across a lowtension source and a transformer primary; the connexion to the source is broken before the transformer connexion is completed, and the connexion between the condenser and the primary is broken at the moment when the condenser discharge current passes through zero. The condenser is connected across the supply mains in one position of a commutator switch j rotated by a shunt motor p. As the switch rotates, this connexion is broken and the condenser is connected across the primary winding f for discharge. The condenser may be divided into two parts a<1>, a<2>, as shown, and a switch w controls the connexions to give a small, medium, or large capacity. The speed of the motor p can be varied by the shunt-field rheostat p<2>.

Title: Improvements in or connected with the frames of motor tractors, agricultural implements, and the like
IPC: B62D51/00
Filed: 1930-04-01
Abstract: 352,393. Implements for working land; tractors. MOTE, H., 4, Park Place, St. James, London. April 1, 1930, No. 10321. [Class 6 (i).] In agricultural implements or tractors the running wheels or endless tracks on opposite sides are independently mounted and are connected by transverse equalizers to the frame so that the frame may be maintained level by reason of the centre of gravity being low down or by the operator walking behind irrespective of any irregular up and down movement of the wheels &c. In the construction shown in Fig. 1, the frame is supported on endless tracks 19 one on each side, the tracks being driven from a transverse differential countershaft 3, mounted on the main frame 1 through chains 22 contained in independent casings 10 forming radius rods. The weight of the frame 1 is transmitted to the endless tracks through vertical arms 12 pivoted to the ends of a transverse equalizing bar 14, the centre of which is connected to a longitudinal lever 8 pivoted at its forward end to a cross member connected to the frame 1 by the vertical supports 7. The other end of the lever 8 may be raised and lowered relatively to the frame 1 by the operator and is retained in position by a catch 8b engaging teeth in the vertical rack 9 carried bv the frame 1. Two arms 42 on the frame 1 enable the operator to hold it and the cultivator tines 23 horizontal irrespective of the independent vertical movements of the endless tracks, while the adjustment lever 8 enables the tines to be raised clear of or lowered into contact with the ground. In the alternative construction shown in Figs. 3 and 4, endless tracks are similarly connected to the frame, but their up and down movements are controlled by the engagement of toothed sectors 25, 26 with sectors 31, 32 carried on shafts 29, 30 on the main frame 6. The sectors 31, 32 rotate with sectors 33, 34 over which run flexible wires 52, 53 to the ends of an equalizing member 46 which turns about a vertical pivot 45. Springs 56 tend to raise the frame 6. The centre of the equalizing lever 46 is adjusted forwardly or rearwardly by a connection 37, 39 to a handlever 40, within reach of the operator who may thus raise or lower the main frame and render the ploughshares 67 operative or inoperative as required. The frame 6 is maintained horizontal by the handles 42 whatever the up and down movements of the endless tracks. When two pairs of wheels or endless tracks are provided, the operator may ride on the machine and the centre of gravity is then low down to ensure stability.

Patent GB-573689-A (GB)
Title: Improvements in or relating to the production of pest control agents
IPC: C07C17/02
Filed: 1942-07-27
Abstract: Benzene is chlorinated in the presence of actinic radiation to produce a mixture of benzene hexachloride isomers.  The chlorination may be continued until a slurry is produced in which the solid matter is mainly the a  isomer, b  and g  isomers remaining in solution. The a  isomer, containing some g  isomer may be filtered off and the g  isomer separated from the mother liquor by recrystallization, benzene may be evaporated from the slurry to leave a mixture of isomers.  Alternatively, the chlorination may be interrupted before solid matter separates, the solution being run into hot water to flash off the benzene leaving a mixture of a  and b  isomers in solid form with the g  isomer as a liquid adhering to them.  The hot mass is then poured into cold water to produce a mixture of the three isomers.ALSO:A composition for use as a pest control consists of benzene hexachloride prepared by the additive of chlorination of benzene in the presence of actinic radiation and therefore containing a significant proportion of g -benzene hexachloride or a solution thereof in admixture with a carrier or diluent which is a non-solvent for the hexachloride.  According to a modification the g -isomer itself or a solution thereof is used in admixture with the carrier &c.  The benzene hexachloride may be mixed with a solid diluent such as chalk, gypsum, slatedust, talc or made up as a water dispersible powder with an agent such as goulac or soap or may be emulsified with water, e.g., after solution in benzene or dibutyl phosphate.  It may also be mixed with a bait material. The chlorination may be carried on until a slurry is produced in which the solid matter is mainly the a  isomer, b  and g  isomers remaining in solution.  The a  isomer containing some g -isomer may be filtered off and used for the production of pest control agents and the g  isomer separated from the mother liquor by crystallisation to produce agents of high potency, or the slurry may be evaporated to drive off benzene to leave a mixture of the three isomers.  A preferred method is to interrupt the chlorination before solid matter separates, run the solution into hot water to flash off the benzene leaving a mixture of a  and b  isomers in solid form with the g  isomer as a liquid adhering to them.  The hot mass is then poured into cold water to produce a mixture of the three isomers in solid form.  U.S.A. Specification 2,010,841 is referred to.  The first Provisional Specification is not restricted to preparations containing the g isomer and refers to Specification 504,569, [Group IV].

Class 20(ii) A telescopic pit-prop in which the inner part 1 carries with it a wedge 4 during part of its movement into the lower part 2 by means of a coupling which is automatically releasable from the inner part. This coupling may comprise a stirrup embracing the prop and wedge and tightened by an eccentric annular member rotatably mounted on the stirrup, or a wedge, which are released by engagement with the lower member. As shown in Fig. 3 the coupling comprises a stirrup 5 pivoted to the wedge 4 and surrounding the part 1, which it grips when tilted but from which it is released when it has descended to engage the lock 3 on the lower part 2. The wedge 4 bears against an .inclined face on an abutment 7 in the lock 3, the locking device being tightened or released by a wedge or eccentric which moves the abutment 7 to or from the wedge 4. As shown in Fig. 3 one side of the stirrup has a pivoted pressure member 11 and the stirrup is pivoted to the wedge by a pin 9 in a slot 10, the pin 9 being below the pivot pin of the pressure member 11 to cause the stirrup to act as a toggle lever and so to obviate its jumping back to a level position. A toggle lever may be arranged between the pin 9 and the member 11 to increase the pressure of this member .on the part 1. The. stirrup may be round in cross-section and rest loosely on top of the wedge without being pivoted. In Fig. 5 a friction plate 12 is shown attached to the stirrup 5 to ensure that the stirrup 5 tilts when the inner part 1 descends. To facilitate release of the prop a spring may be placed below the wedge 4 and/or, in Fig. 5, below the friction plate 12.
